If you think they’re just friends, you’ve got another thing coming!
While the duo arrived one after the other to The Standard Hotel for the after-party last night, they were inseparable once inside.
According to some sneaky spies at the event, Katy and Johnny Boy were very much together — they spent the majority of their evening side-by-side, as well as chatting with other celebs together.
The twosome were also spotted locking lips and holding hands inside the Boom Boom Room at the hotel!!
This relationship is SO on again.
Cheers to the happy couple!
